You typed the udevinfo command wrong. You typed:bob@t40:~$ udevinfo -a -p `udevinfo /dev/sda1`It's supposed to beudevinfo -a -p `udevinfo -q path -n /dev/sda1`Basically, "udevinfo -q path -n /dev/sda1" which means give me the sysfs device path (-q path) for node sda1 (-n /dev/sda1). Pass this to the second udevinfo command "udevinfo -a -p `...` ", meaning give me all the sysfs attributes (-a) for this sysfs device path (-p).
bob@t40:~$ sudo udevinfo -a -p `udevinfo -q path -n /dev/sda1` couldn't get the class device Thank you John. Bob
